Haemostatic procedures such as preperitoneal pelvic packing (PPP), pelvic angiography (PA), and internal iliac artery ligation are used for haemorrhage control in pelvic fracture patients with haemodynamic instability. Pelvic external fixation (PEF) and pelvic binder (PB) are usually applied with haemostatic procedures to reduce the pelvic volume. This study aimed to compare the clinical outcomes between patients who underwent PEF and PB. Among 173 patients with pelvic fracture admitted to the emergency room of three regional trauma centres between January 2015 and December 2018, the electronic charts of haemodynamically unstable patients were retrospectively analysed. Among the 84 patients included in the analysis, 20 underwent PEF with or without PB, and 64 underwent only PB. There were significant differences in tile classification and laparotomy between the PEF and PB groups ( p  = 0.023 and  p  = 0.032). PPP tended to be more frequently preformed in the PEF group ( p  = 0.054), whereas PA tended to be more commonly performed in the PB group than in the PEF group ( p  = 0.054). After propensity score matching to adjust for differences in patient characteristics and adjunct haemostatic procedure, there was no significant difference in 7-day, 30-day, and overall mortality rates between the PEF and PB groups (10.5% vs 21.1%,  p  = 0.660, 21.1% vs 26.3%,  p  = 1.000, and 26.3% vs 26.3%,  p  = 1.000). Cox proportional hazard regression analysis and multivariate analysis for correction of covariates (age, lactate, and abdominal injury) showed that PEF was not an independent factor for 30-day mortality compared with PB (adjusted hazard ratio, 0.526; 95% confidence interval, 0.092–3.002;  p  = 0.469). Among the volume reduction procedures performed with other haemostatic procedures in patients with pelvic fracture and haemodynamic instability, PEF did not significantly reduce the 30-day mortality rate compared to PB.
